Tennessee - Development 1 case study

Wild Briar Ridge is a 70-lot residential development located in the shadow of the Smoky Mountains in East Tennessee. The developers of this subdivision were faced with the prospect of building in a pristine rural setting without the advantages of urban infrastructure such as sewer. The success of managed decentralized technology provided the solution needed.

In 2004, the developers of Wild Briar needed technology that would provide wastewater treatment in an area that would be traditionally served by individual onsite systems. The problems presented by the site included shallow soil over sloping bedrock and excessive slopes. The conditions would not support more than a few individual systems. The developers chose a SCAT Aerocell cluster with drip irrigation. This allowed the construction to begin in the summer of 2005 and final start-up of the system occurred in March 2006.

The treatment system consisted of 24 SCAT Aerocell modules located at the bottom of the development. All the building lots are located upslope from the treatment cluster that allow for collection of the wastewater by STEG and STEP systems located on each lot. The wastewater is then sent to a tank farm consisting of a 25,000 gallon recirculation tank. The wastewater is then dosed to the treatment cluster. The returning treated water is split with 80% going back for treatment and the remaining 20% being discharged to a 15,000 gallon drip dosing tank. After ultra-violet disinfection, the treated water is then dosed to a 6 zone drip field. The drip system was placed in two large fields located at the bottom of the development and was installed using a vibratory plow.

The system is maintained by a level 5 management entity that sees to routine maintenance and performs mandatory testing as required by the Tennessee Department of Environment and Conservation. The utility management assures that the future needs of the public will be served in this development.

In conventional treatment of variable quality mountain water, an inability to immediately adjust the coagulant dose to variations in water quality causes overdose or underdose of coagulant in relation to its optimal value. The results of the research showed that the reuse of post-coagulation sludge was an effective method to maintain high and stable coagulation effectiveness under both polyaluminium chloride (PACl) overdose and underdose conditions. Recycled sludge contains a large portion of insoluble aluminium...

One key technology to eliminate organic micropollutants (OMP) from wastewater effluent is adsorption using powdered activated carbon (PAC). To avoid a discharge of highly loaded PAC particles into natural water bodies a separation stage has to be implemented. Commonly large settling tanks and flocculation filters with the application of coagulants and flocculation aids are used. In this study, a multi-hydrocyclone classifier with a downstream cloth filter has been investigated on a pilot plant as a space-saving...

Located on the eastern side of the San Francisco Bay, the East Bay Municipal Utility District (EBMUD) treats and distributes water to over 1.3 million customers in Alameda and Contra Costa counties. As one of the largest utility districts in California, EBMUD is a leader in the water industry’s water quality, conservation and sustainability efforts.
EBMUD chloraminates water prior to distribution and uses chloramines for secondary disinfection in order to mitigate DBP (disinfection byproduct) formation....

The effects of poly aluminum chloride (PACl) dosing positions on the performance of a pilot scale anoxic/oxic membrane bioreactor were investigated. PACl dosage was optimized at 19.5 mg Al2O3/L by jar test. Nutrients removal efficiencies and sludge properties were systematically investigated during periods with no PACl dosing (phase I), with PACl dosing in oxic tank (phase II) and then in anoxic tank (phase III). The results showed that total phosphorus removal efficiency increased from 18 to 88% in phase...

Poor sedimentation of the active sludge in the secondary clarifiers;
Poorer sludge dewatering results: lower solids content in dewatered sludge;
Greasy...
